Backing up Office 365 best practices?

[finsfree]

I'm testing out Veeam Backup for Office365. Which is a better way of backing up your companies data one BIG backup job or several little backup jobs. I have 200 users at my job and they all have email, one drive and sharepoint.

Thanks,

We have a best practice guide available. we advise to split the data so that would mean 3 jobs.
